Widget not showing on VSCode with Remote SSH

[tjahn]

Hello,

I am on MacOS and using itkwidgets 0.32.0 on VSCode 1.55.2 to work on a remote Linux Server using the Remote-SSH Extension 0.65.1. However, the itkwidget is not showing up in the interactive python console. I set the python.loggin.level to debug, but didn't see any meaningful errors or warnings in the Jupyter and Python output console.

This here is my test script:

import numpy as np
from itkwidgets import view
image = np.random.rand(100,100)
view(image)

When running the same script locally, without the Remote Extension, the widget is working nicely. It even works, when I connecting to an existing Jupyter server running on said remote Linux Server.

It might not be correlated, but when I tried adding "jupyter.widgetScriptSources": ["jsdelivr.com", "unpkg.com"], to the remote ssh settings I got this VSCode warning when running the test script:

Unable to load a compatible version of the widget 'itkwidgets'. Expected behavior may be affected.

Hi @tjahn,

Thanks for the report and detailed information!

To confirm, when using in VSCode, the widget is used as a JupyterLab widget versus a Jupyter Notebook widget?

Thanks, Matt

seeing a similar thing here. remoting into linux, using itkwidgets.view shows nothing (but no error either):

FWIW: If I click the ... next to where the widget, I have the option to pick a renderer (one shows the text repr, the other shows the empty space)

@thewtex, lemme know if I can help troubleshoot! thanks :)

I reproduced this locally.

@oeway with the recent itkwidgets ImJoy upgrade and with the ImJoy VSCode extension install, there still is no output. How could we get ImJoy window in the VSCode Jupyter output?

[oeway]

Hmm, I think it's a bit tricky to get it work there, it's not a normal Jupyter environment as I understand, to get it work we need a way to do bidirectional messaging between the editor and the kernel, plus a way to show the iframe. In the normal Jupyter we used Comm messages, I am not sure if that is available and what need to be adjusted.

I will need to check it out.

same issue

I have the same issue, though I am not sure it is only related to VSCode: when I start the jupyter notebook server directly on the remote machine, and connect to it using Firefox (with Google Chrome I am getting a similar error), I am getting the following error message instead of the itkwidget box:

[Open Browser Console for more detailed log - Double click to close this message]
Failed to load model class 'ViewerModel' from module 'itkwidgets'
makeError@http://localhost:8888/static/components/requirejs/require.js?v=f0cc8bbb2fcef87fc194fecbb632fcfa:168:17
onScriptError@http://localhost:8888/static/components/requirejs/require.js?v=f0cc8bbb2fcef87fc194fecbb632fcfa:1738:36

Sometimes it even crashes the kernel. I looked into the Browser Console, but the error message is the same. Any idea? Thanks in advance!

any updates on this ? same problem.

I could use itkwidgets.view on browser but now I can't. The same error. Is there any update?

Same with ipywidgets

[thewtex]

Looking into the details, VSCode's Notebook extension support is extremely limiting. For a first pass, that will enable all itkwidgets functionality and work with different VSCode deployments (local, remote, GitPod, GitHub Codespaces, etc.), we could leverage #589 along with an extension that previews a python-driver server content.

Is it working on WSL or remote-ssh? Widgets not showing on vscode

My version is 1.0a35

@thewtex

[thewtex]

@ubless607 the experimental CLI support works in VSCode's terminal and remote ssh WSL.

any updates on this ? same problem on remote with k8s
